You've hit a tricky part.  The "specs" file goes in a different place
when you're cross compiling.  Mine is in (for example):

	/usr/local/lib/gcc-lib/i386-go32-msdos/2.7.2/specs

The specs file gives the extra linker argument -Tdjgpp.lnk and
djgpp.lnk is also in (for example) (with the .a files):

	/usr/local/lib/gcc-lib/i386-go32-msdos/2.7.2/djgpp.lnk

Try using "gcc-dos -v hello.c -o hello.exe" instead.  That will help
you figure out the paths and such.
